Information Transmitting Method and Device and Information Receiving Method and Device

1. A method for increasing privacy of transmitted information, comprising: selecting, by a user at an information transmitting device, a target transmission mode from transmission modes for a to-be-transmitted short message, the transmission modes include a disappear-after-reading transmission mode and a normal transmission mode, the disappear-after-reading transmission mode indicates that the to-be-transmitted short message is to be deleted, from a receiving device, once viewed, and cannot be saved at the receiving device; on a condition that the target transmission mode is the disappear-after-reading transmission mode, prompting the user whether to back up the to-be-transmitted short message to a backup server; in response to receiving from the user a command to back up the to-be-transmitted short message to the server: adding, by the information transmitting device, a backup tag to the to-be-transmitted short message, the backup tag indicating that the to-be-transmitted short message is to be deleted, from the receiving device, once viewed, cannot be saved at the receiving device, and is subsequently viewable from a server; and backing up the to-be-transmitted short message to the server; and in response to receiving, from the user, a transmission command, transmitting, by the information transmitting device, the to-be-transmitted short message to an information receiving device.

2. The method of claim 1 , wherein backing up the to-be-transmitted short message with the backup tag to the server comprises: determining whether a password corresponding to the information transmitting device is saved on the server; and backing up the to-be-transmitted short message to the server when the password corresponding to the information transmitting device has already been saved on the server, and extracting attribute information of the to-be-transmitted short message as search keywords to enable the information receiving device to search for the to-be-transmitted short message based on the search keywords.

3. The method of claim 1 , further comprising: prompting the user to create a password when the password corresponding to the information transmitting device is not saved on the server.

4.

7. The method of claim 6 , wherein extracting the short message backed up on the server for the user to read further comprises: prompting the user to input a password corresponding to the backup short message, and verifying whether the password is input correctly; and when the password is input correctly, extracting the short message backed up on the server for the user to read.

8. The method of claim 6 , further comprising: in response to the user closing the short message and the short message comprising the disappear-after-reading tag, deleting the content of the short message from the information receiving device.

9. The method of claim 6 , further comprising: displaying the received short message associated with the backup tag or the disappear-after-reading tag, wherein: when the short message is not opened, the short message is displayed in a first display style; and when the short message is opened, the short message is displayed in a second display style.

10. The method of claim 9 , further comprising setting at least one of the first display style and the second display style in response to receiving a setting command.

11. An apparatus for increasing privacy of transmitted information, comprising: a storage unit storing a plurality of computer-readable program codes; and a processor electrically connected to the storage unit and configured to execute the plurality of computer-readable program codes to: select, by a user, a target transmission mode from transmission modes for a to-be-transmitted short message, the transmission modes include a disappear-after-reading transmission mode and a normal transmission mode the disappear-after-reading transmission mode indicates that the to-be-transmitted short message is to be deleted, from a receiving device, once viewed, and cannot be saved at the receiving device; on a condition that the target transmission mode is the disappear-after-reading transmission mode: prompt the user whether to back up the to-be-transmitted short message to a backup server; in response to receiving from the user a command to back up the to-be-transmitted short message to the server: add a backup tag to the to-be-transmitted short message, the backup tag indicating that the to-be-transmitted short message is to be deleted, from the receiving device, once viewed, cannot be saved at the receiving device, and is subsequently viewable from a server; and back up the to-be-transmitted short message to the server; and transmit the to-be-transmitted short message to an information receiving device.

12. The apparatus of claim 11 , wherein the plurality of computer-readable program codes to back up the to-be-transmitted short message with the backup tag to the server further comprise computer-readable program codes to: determine whether a password corresponding to the apparatus is saved on the server; and back up the to-be-transmitted short message to the server when the password corresponding to the apparatus has already been saved on the server, and extract attribute information of the to-be-transmitted short message as search keywords to enable the information receiving device to search for the to-be-transmitted short message based on the search keywords.

13. The apparatus of claim 11 , wherein the processor is further configured to execute the plurality of computer-readable program codes to: prompt the user to create a password when the password corresponding to the apparatus is not saved on the server.
